Low concentration of $K^+$ and high concentration of $Na^+$

Vedclass · Answer

(C) In a resting state,the axonal membrane is more permeable to $K^+$ ions and nearly impermeable to $Na^+$ ions. Due to the action of the $Na^+-K^+$ pump,which actively transports $3$ $Na^+$ ions outwards for every $2$ $K^+$ ions brought into the cell,the extracellular fluid (outside the axon) maintains a high concentration of $Na^+$ ions and a low concentration of $K^+$ ions. Conversely,the axoplasm (inside the axon) has a high concentration of $K^+$ ions and a low concentration of $Na^+$ ions. Therefore,the correct option is $C$.

Assertion: The imbalance in concentration of $Na^+$,$K^+$ and proteins generates resting potential.
Reason: To maintain the unequal distribution of $Na^+$ and $K^+$,the neurons use electrical energy.
